IMPROVEMEET IN QUARTZ-RUSHBBS.

T ALL WHOM IT MAY CONCERNE 'B il: known that I, CARLILE MAS ON, cf thecityof Chicago, in the county of Cook, and State of Illinois, have inventedia certain new, useful, and improved Machine for Breaking, Crushing,.or Pulveiizing Quartz Rock, Goal, or other substances; and I do hereby d eclare that the following is a full, clcar, and exact description of the samc, reference being had to the accmpanying drawigs, making a part of this specification, in which- Figure 1 isa top view.

Figure 2, a. longitudinal section et the red line U. V

Figure 3, a. transverse section on.the line k-l; and

Figure 4, a front:view -of the sining-hesm w.

Like letters refer' to similar parts in all of the figures.

The nature and object of m'y' invention consist in constfucting a crushing machine by s0 arrginging twc .meta1lic cones that their apices will be near1y in contact, the axis of each being inclined so that on one side of the apies the surfaces w ill be parallel to each other and nearly in contact; the cones re volving on thcir axis, any substance placed between the canes at their open sides Will be taken up and compressed, and when br'ought to the point'wheie the, surfaces are nar ly or quite in contact, wil1 then be thoroughly crushed and Pulverized; and in providing su(ih machine Wth tension-rods andsprings to prevent breakng the'Lmachine when any substance gctS ntothc machine whch s beyond its power to crash.

A To nab1e others ski1led in the art to its construction and operation.

a 6 a d e f g hn etesents a frainework of tiniber firmly b olted together. m mare two conica1faced heads, fixed to the inner ends cf the-shaits n-n. These shafts n n rest on the cross-beanis e h and f, working in the boxes'o p q 7'? represent two beelled cog-wheels, attached to the 'shaftsn 71 c is the driving-shaffg, which is .proyidcd w'itha drum, n, at one end and a. fiy-whee1, v, at the other. To this shaft are also attached two pinion-whls, H, by which 'the whe els r r a1:e driven. w w represent -two springbeams, bolted to the aides of the frame, as shown. x ce a: a: represent four tension-bars orrods passing through s1ots or ho1es in the frame, and are conneted by the pins y y on the outside 'of the Springbeams w w. 'lhe pins y y are fitted in the boxes zz. On one or both sides (one shown) Wedgcs a a ar',driven in between the box 2 and the spring-beam w, (figS. 1' and 3,) by means of Which the tension of the bars av and the space between the eonica1 heads .m is adjus'ted. The bars :1: are connctedai. the cnds of the machine by the cross-heads I) I) and pins c c. Through these cross-headS 6 are passed screws 6, which' pass into the boxes 0 and q, or into one of them, tdreceive the 1atera1 pressure upon the shafts n, and they are also used in adjusting the space hetxveen the conica1 heads me when the keys or wedges a a site insufficieht. The upper half cf the box 0 make and use my invention and machine, I wi1l proceed todescribe (fig. 1,) beingremoved, shows the position and office of these screws. s s represent springs placed between.

the springbeams in 'and frame to strengthen the spring-beams. g is a feeding-trough or hopperl 7/is concave shield or fender, par.tia1ly surrounding the conical heads m and near1y in contact with the peripher of the heads. This fender is attached to the beam 6 of the frame. The conica1 hen ds m mare corrugated r in consecutiveicircles,asshown, or otherwise, to prevent the material -from slipping Whi1e bing cOmpressed or crushed. When the machine is fully constructed power is applied to the drum u attached to the shaft s, upon which are Placed thepinion-wheels t t, and from these pinions communicated to the cog-v vheels r 7' on the shafts u u, and the conical heads m m revolved; and in their revoiution they .present two surfaces which are constantly apProaching each other and-coming nearly or quite in contact; and thus form, by their graduel v approach, a powerful crusher whi ch wi1l crash or pulverize or simply crush, as the hea ds are brought together or separated -'Rigidity of the machine is' avoided by the sysccm cf tension-bars or rods cross-heads b, springbeams w, 50 that if iro n or any substance which it is' impossibleto crash gets into the machine it Will not thereby be broken. Thdistanc betiveen the conical heads is regulated and adjusted by the screws e e,

which beur against thcends of the shafts n n, and by the keys or wedges a (1 of the*tension frame.

I t W111 be obvios that-the machine needs to be made" of great strength, and Whcnso made W111 be found to
